Description
Cellulose acetate (CA) membrane filter is an unsterile laboratory membrane for microbiological and particle-related work. Membranes in this range are made from cellulose nitrate (cellulose mixed ester), cellulose acetate, or regenerated cellulose and support colony count determination, particle testing, and microscopy. Users can select unsterile membranes with or without a grid, and with or without a hydrophobic edge, according to counting and handling needs. This variant is supplied as 1 piece, with a net weight of 0,092 kg and gross weight of 0,096 kg, suited to single-use or low-volume setups. Cellulose acetate membranes are widely applied when clear colony visualisation, particulate assessment, or microscopic examination of retained material is required. Non-sterile format fits protocols that do not demand pre-sterilised discs. Origin is Germany. Available from manufacturer Sartorius, this CA membrane filter complements standard microbiology and quality-control filtration workflows where unsterile cellulose-based membranes are specified for colony enumeration, particle checks, or microscopy sample preparation.

Questions about CA white -black HE, non-sterile, 0.45
What is this article?
CA white -black HE, non-sterile, 0.45 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Carbohydrates & sugars, inside Biochemicals & reagents, in Microbiologie.
A carbohydrate reagent is a sugar or a derivative, specified by identity, anomer where it matters, and purity. Hydrate and anhydrous forms change the mass. A culture-grade sugar and an analytical standard of the same name are different bottles.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
